Refreshes one or more indices. For data streams, the API refreshes the stream's
|
|
backing indices.

==== {api-description-title}
|
|
|
|
Use the refresh API to explicitly refresh one or more indices.
|
|
If the request targets a data stream, it refreshes the stream's backing indices.
|
|
A _refresh_ makes all operations performed on an index
|
|
since the last refresh
|
|
available for search.
|
|
|
|
// tag::refresh-interval-default[]
|
|
By default, Elasticsearch periodically refreshes indices every second, but only on
|
|
indices that have received one search request or more in the last 30 seconds.
|
|
// end::refresh-interval-default[]
|
|
You can change this default interval
|
|
using the <<index-refresh-interval-setting,`index.refresh_interval`>> setting.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
Refreshes are resource-intensive.
|
|
To ensure good cluster performance,
|
|
we recommend waiting for {es}'s periodic refresh
|
|
rather than performing an explicit refresh
|
|
when possible.
|
|
|
|
If your application workflow
|
|
indexes documents and then runs a search
|
|
to retrieve the indexed document,
|
|
we recommend using the <<docs-index_,index API>>'s
|
|
`refresh=wait_for` query parameter option.
|
|
This option ensures the indexing operation waits
|
|
for a periodic refresh
|
|
before running the search.
